BOX-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 792,583, dated June 20,1905.

Application filed August 12, 1903. Serial No, 169,294.

To all 1071/0712! it may concern.-

Be it known that I, J ACOB M. CARNonoss, a citizen of the United States,residing at Jackson, in the county of Jackson and State of Michigan,have invented a new and useful Box- Making Machine, of which thefollowing is a specification.

My invention relates to box-making machines, and especially to a machinefor forming the heads or ends of paper boxes, and has for its objects toproduce a device of this character of simple construction, which will beeificient in operation, one in which one boxhead may be formed whileanother is drying, thus permitting a continuous operation of themachine, and one from which the box-heads after completion may bereadily removed.

To these ends the invention comprises the novel details of constructionand combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a vertical longitudinalsectional elevation. Fig. 2 is a horizontal section plan on the line 2 2of Fig. 1. Fig. 3 is a detail View. Fig. at is a similar View on theline 4 4 of Fig. 1.

Referring to the drawings; 1 indicates a supporting-base, from whicharises a vertical cylindrical shaft or spindle 2 for sustaining a rotaryframe 3. The rotary frame of the machine consists of a vertical tubularsleeve or hub journaled upon the shaft, provided at its lower end withthree horizontal radiating arms 4, each terminating at its outer end ina head 5, having a central vertical opening- 6, and at its uppcrend withthree horizontal arms 7, terminating in heads 8, having central openings9, these upper arms being in vertical alinement with the lower arms.

The rotary frame 3 carries three sets of box-forming mechanisms; butinasmuch as these mechanisms are all identical in construction andoperation I will describe but one in detail. In each of said mechanismsindicates a vertically-movable primary die fixed upon a shaft 11,mounted for vertical reciprocation in the opening6 of head 5. Foractuating the shaft, and consequently the die, I employ a lever 12,pivoted at its upper end, as at 13, in a bearing carried by the head 5and acting through a substantially horizontal link 14: uponsuitabletoggle-links 15, the upper of which is pivoted to the lower end of theshaft and the lower to a horizontal journal or pintle 16, carried by apair of spaced vertical arms or standards 17 attached at their upperends to and depending from the head 5, the links being connected attheir central pivotal joint to the link 14:. From this construction itwill be seen that when the lever 12 is swung inward the links 15 inassuming a position in vertical alinement will, through shaft 11, forcethe die 10 upward, while a reverse movement of the die will follow uponthe lever 12 being swung outward. At this point it is to be noted that Imay, if found expedient to do so, dispense with this particularmechanism for operating the die and employ instead a hand-wheel andscrew or compressed air and that such a change would not amount toadeparture from my invention.

In practice thedie 10 receives the body po rtion or blank of thebox-head, which is maintained thereon by an annular band or member 18,arranged to loosely encircle the die and embrace the blank. The member18 is provided with a plurality of arms or pins 19, which dependvertically from its lower edge through guide-openings formed in a flange20 upon the lower end of. the die, and fixed upon the upper face of thehead 5 is a member 21, carrying radiating arms 22, designed to engagebeneath the pins 19 to hold the ring in fixed position during downwardmovement of the die, whereoy the box-head will be discharged therefromwhen desired. The member 21 is capable of a slight rotation controlledby a pin 23, disposed in a slot or opening 24:, in orderthat the arms 22may, when circumstances require, be moved from beneath the pins, thuspermitting the ring to normally move with the die, under whichconditions the ring will fall by gravity to a point about central of thedie and rest upon supporting pins or members 25.

In forming the box-head the primary die 10 cooperates with a secondarydie 26, fixed upon the lower end of a vertical shaft 27, externallyscrew-threaded throughout a portion of its length. This shaft isvertically movable in the opening 9 of head 8 and is slottedlongitudinally, as at 28, for engagement with a horizontal pin 20,carried by thehezuhwhereby rotation of the shaft is prevented. The shaftis reciprocated vertically by means of a hand wheel 30, having a hubinternally threaded for engagement with the threaded portion of theshaft, said hub being provided at its upper end with a flange 31,engaging flanged members 32, fixed to the head 8. By this arrangen'ientthe die 26 can be adjusted to the proper position relative to die 10 byrotating the hand-wheel 30, the die after being brought to the properadjustment remaining fixed d u ring the operation of the device.

Mounted upon and encircling the die 26 is an annular band or crimpingmember 33 of a length somewhat greater than the length of the die andextending slightly beneath the lower end of the latter. The extended endof the member is outwardly flared, preferably by beveling its innerface, as at 34, the purpose of which will presently appear. This memheris adjustably secured upon the die by means of horizontal arms 35, whichradiate from thehub of the latter and have their outer ends disposedeach in a substantially Z-shaped aperture formed through the wall of thering, whereby the latter may be adjusted vertically upon the die to anupper or lower position and fixed in either of said positions by aslight rotation, bringing the horizontal portions of said apertures intoengagement with the arms. The ring is also provided through its sidewall, just above its flaring mouth, with a horizontal slot 36, throughwhich the disks of paper forming the end of the box-head may beintroduced when the member in the lower of its two positions.

In practice the blank for forming the body portion of the box-head isplaced upon the die 10, upon the end of which there is also arranged adisk of pasteboard or the like constituting the inner member of the end.The die it is then brought to the proper adjustment in the manner abovedescribed with the ring 33 adjusted thereon to its upper position.Inward movement of the lever 12 now serves to move the die 10 upward, asheretofore explained, whereby the upper edge of the bodyblank, whichprojects slightly above the die, will contact with the inner bevel 34:of the crimping member and be thereby turned inward over and upon theend of the die and the disk thereon. The die 10 is now moved downward inorder that paste may be applied to the overturned edge of thebody-blank, and the crimping member is adjusted to its lower positionupon the upper die, and a disk or blank forming the outer end member ofthe head is inserted to position through the slot 36. Die 10 is thenagain moved upward, whereby the outer disk will be pressed upon theouter end of the box-head, the parts being allowed to remain in thisposition until the paste dries,

after which member 21 is moved forbringing its arms 22 beneath the pins19 and the die 10 is moved downward, whereby the com pletcd box-headwill be discharged, owing to the holding of the ring 18 againstmovement, as hereto'fore described.

\Vhile the paste or cement is drying upon one of the box-heads the frame3 may be rotated for bringing another box-forming mechanism to position,and a second head may be formed thereby in a manner identical with thatabove described, and so on until the firstformed head has dried and beendischarged in its completed state, thus rendering the operation of themachine continuous.

From the foregoing it will be seen that l. produce adevice of simpleconstruction, which in practice will admirably perform its functions tothe attainment of the ends in view; but it is to be understood that l donot limit myself to the precise details herein set forth, inasmuch asminor changes may be made therein without departing from the spirit ofthe invention.

Having thus described my invention, what I claim is 1. in a box-machine,the combination with a frame, of a reciprocatory shaft sustainedthereby, means for reciprocating the shaft, a primary die carried by theshaft, means for maintaining a blank upon the die, a secondary die, acrimping member associated therewith, a screw-threaded shaft movablysustained by the frame, and a hand-wheel for actuating the shaft toadjust the secondary die relative to the primary die.

2. .In a box-machine, the combination with a frame, of a reciprocatoryshaft sustained thereby, means for reciprocating the shaft, a primarydie carried by the shaft, a blankholding member embracing the die, meanspermitting said die to move independently of said member, a secondarydie, means for sustaining the same, and a crimping member as sociatedwith the secondary die.
